MARCUS A. ADLER, OF NEW YORK, N. Y.

MACHINE FOR CUTTING TEXTILE AND OTHER MATERIALS.

SPECIFICATION forming part of Letters Patent No. 236,527, dated January 11, 1881.

Application filed September 22, 1880.

To all whom it may concern:

Be it known that I, MARCUS A. ADLER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Machines for Cutting Textile or other Materials, of which the following is a specification.

This invention relates to that class of cutting-machines comprising a platform which is movable beneath the material to be cut, thus supporting such material adjacent to the cutting-point.

It consists in certain novel combinations of parts, hereinafter fully described, and pointed out in the claims.

This invention is illustrated in the accompanying drawings, in which Figure 1 represents a vertical longitudinal section. Fig. 2 is an inverted plan view. Fig. 3 is a detail view of the cloth-lifter.

Similar letters indicate corresponding parts.

The letter A designates the platform, which is preferably beveled to facilitate its introduction and movement beneath the material; and B, a knife constituting the cutting-instrument. This knife is stationary, and the cloth or other material to be out is subjected to its action by means of a lifting device, 0, which, for convenience, I term a clothlifter.

The cutting-edge of the knife B is preferably inclined, as at d, and in order to enable the cloth-lifter G to raise the material against such edge it is provided with a slot, 6, Fig. 3, of sufficient width to admit the knife while it is set to pass within or beyond the cuttingedge, as indicated in Fig. 1. As the material rises with the cloth-lifter C it is kept in a flat or spread condition by means of a presser-foot, F, which is located above the clothlifter, and whose action is produced by a spring, g, so that it yields to the motion of This presser-foot F is provided with a slot, h, Fig. 1, adapted to admit the knife B, and, like the cloth-lifter 0, it passes within or beyond the knife-edge.

A cam, I, is used for raising the presserfoot F, and the latter, as well as the knife 13, is applied to a standard, J, rising from the (No model.)

platform A, the knife being preferably made adjustable. To the standard J is also applied a handle, K, for guiding the machine.

The platform A is mounted on wheels N N O, and in this example motion is given to the cloth-lifter O by amechanism connected to the wheel N-that is to, say, the cloth-lifter O is made in the form of a plate, which is hung on a shaft, 19, and constitutes one arm of a bellcrank, the other arm of which is connected with an eccentric, Q, fixed to a shaft, 1', which is geared with the wheel N by cog-wheels S S S Other means, however, may be adopted for operating the cloth-lifter O-as, for example, a spring-power or a hand-crank arranged on the platform, or it may be connected with steam-power, and instead of a plate the lifter v may be constructed in the form of a reciprocatin g slide or a revolving cam.

WhatI claim as new, and desire to secure by Letters Patent, is-

1. In a machine for cutting textile or other materials, the combination, with a platform movable beneath the material to be out, of a stationary knife, a cloth-lifter acting automatically from below the cloth to bring the same up against the knife, and a means for imparting a vibratory motion to the cloth-lifter, all constructed and adapted to operate substantially as described.

2. In a-machine for cutting textile or other materials, the combination, with a platform mounted on wheels to move beneath the material to be cut, of a stationary knife, a vibratory cloth-lifter, and a mechanism for imparting motion to the cloth -lifter connected to one of the platform-wheels, all constructed and adapted to operate substantially as described.

3. In a machine for cutting'textile or other materials, the combination, with a platform movable beneath the material to be cut, of a stationary knife, a vibratory cloth-lifter acting automatically from below the cloth, a

spring presser-foot located above the cloth- IOO movable beneath the material to be cut, of a In testimony whereof I have hereunto set stationary knife, a vibratory slotted clothmy hand in the presence of two subscribing lifter acting automatically from below the cloth witnesses.

a slotted spring pressenfoot located above the MARCUS A. ADLER. 5 cloth-lifter, and a means for imparting motion Vitnesses:

to the cloth-lifter, all constructed and adapted J. HERMANN WAHLERS,

to operate substantially as described. E. F. KASTENHUBER.
